Title: Aimpoint - lower 1/3 cowitness, anyone?
Post by: Hutehund on February 21, 2017, 08:43:29 AM
Am I searching for a unicorn?  I don't want to give up the Scorpion sights.  They're good quality, effective, and perfect for my eyes on my SBR.  There must be a base that will allow a lower 1/3 cowitness with these sights and an Aimpoint Micro.  Has anyone tried this -  LaRue Tactical LT661 Aimpoint Micro Mount?  It looks promising, but I'd prefer not to experiment if there's a known solution.  It doesn't have to be a QR mount.  Has anyone found the perfect Scorpion iron/Aimpoint Micro lower 1/3 cowitness setup?

I installed the Vortex Optics Venom red dot sight 1X3 MOA ($229 Midway) and would highly recommend.

You can set up for co-witness with the iron sights, however I found that a lower-third co-witness works much better for me (red dot sits higher and unobstructed from the front sight).  Target acquisition is much quicker due to the less cluttered sight picture.  But I could still use the iron sights if needed.

I had an extra T2 so I installed it on a Low mount. IMO the highest you'd want on the scorpion is Absolute CW. I've mount My Absolute CW I use on My Tavor on the EVO with the Magpul Z Stock and it works pretty good. So either Low or ACW would be my suggestion

I like Vortex for the price but an Aimpoint is a much higher quality optic. I would not downgrade from an Aimpoint to a Chinese optic just for lower 1/3 cowitness.

The stock Aimpoint LRP mount works just fine in a lower 1/3rd cowitness-ish config. It's probably a bit closer to full cowitness than lower 1/3rd, but it works fine for me.

I have a Burris Fastfire, very similar to the Vortex Venom on a 12 gauge.  I also have a Vortex Sparc II on my AK.  The Scopion is getting an Aimpoint.  I appreciate your replies, and I'll give the Aimpoint LRP mount a try.  Thanks again  :)

Doesn't Geissele make a lower 1/3rd co-witness mount

Most lower 1/3rd cowitness mounts are designed to do so with AR-height irons. Most of the time you're looking at "low" mounts to do cowitness with stuff like HK/CZ long rifles, AKs, etc., as their stock irons sit much lower.

How high does a low mount raise up the red dot? I have a TRS-25 and bought a 1/2inch riser that is too much. 

I would looking for a 1/3 cowitness

Aimpoint HL-1 and it does fine for me. Sorry pics aren't the best.

Also interested.  I want to use a holosun 503G with the ACSS reticle that has BDC hashes.  Those would be obscured by the irons if it's sighted in POI on the irons.  That and I just completely prefer a chevron to a dot because it's a finer aiming point. 

Need a mount that gets the Aimpoint/style optic up a hair above the sight plane of an absolute co-witness of the irons.

Do we know the exact height of the CZ irons so we can math this?  I have a Scorpion inbound and I want to fire off a few more orders so the toys start arriving shortly after.

If a low mount is absolute.  I'm thinking you need about a 1/4" to a 1/3" to get the lower 1/3rd co-witness we'd want.  Question would be, does it exist considering the majority of the mounts are built in relation to the AR's iron sights. 

I guess if push comes to shove the CZ irons could be dumped in favor of AR irons, and I could grab a fortis mount like I already have.  But if we could make something work with the existing irons that would be preferred.

What mount are you using?  I have an ADM Low Mount on my T1 and I can't see the irons.

Looks like the Aimpoint LRP low mount. Silver lever is a dead giveaway.

It's a range toy : If your RDS fails rip it off and use the irons:  IMO trying to CW Iron on this design with a Red Dot is Near Useless

Yes it's a aimpoint LRP low mount. Its not a perfect Co-Witness but if my optic fails I'm still able to use my irons.

I was doing a lot of web searches to try to find the answer and after perusing a thread on ARF the AD-T1-L was given as the answer to a lower co-witness with an Aimpoint type optic. 

And yours blocks the irons?

I have resided to just not cowittness, I do have my optic in a kinetic dev group mount that you can literally grab with one hand and disengage and remove simultaneously

That's what I did too ranastas, no cowitness. Bought an American Defense QD mount for my Vortex Razor. If battery dies and I'm battling zombies, just remove the QD and I can use the iron sights

Yes it blocks the irons when placed on the last bit of the receiver section over the ejection port. If you mount it close to rear sight, the sights are barely visible. I like it further forward.
